[应用][js+css3]3D盒子导航[PC端]

CSS3构建的3D盒子之导航应用

1.在用css3构建的盒子表面，放上iframe，来加载导航页面。

2.鼠标左键按下移动可旋转盒子，寻找想要的网址。

3.左键单机盒子表面，将全屏现实所点盒子表面的网站[iframe中]，并可浏览，关闭后返回原来状态。

4.PC端，将额外显示2个css3做的旋转盒子[没什么意义]

5.移动端只显示一个导航盒子[模拟器正常，真机无效，留待以后查看，兼容开发有待提高。。。]

注：原本打算排列导航盒子，这样的话导航也变得比较好玩

但是，如果使用iframe来显示网站预览的话，速度太慢，太耗内存

尝试过用html2canvas，但是由于跨域问题，直接被灭

解决方法：通过服务器返回较实时的网站预览图的方式显示

1.css3盒子构建：

html:

 <div class="cubeOut" style="left:25%;top:35%">
     <div class='cube move'>
         <div class='face'><iframe scrolling="no" loaded="0" url=""></iframe><div class="label"></div><div class="over"></div></div>
         <div class='face'><iframe scrolling="no" loaded="0" url=""></iframe><div class="label"></div><div class="over"></div></div>
         <div class='face'><iframe scrolling="no" loaded="0" url=""></iframe><div class="label"></div><div class="over"></div></div>
         <div class='face'><iframe scrolling="no" loaded="0" url=""></iframe><div class="label"></div><div class="over"></div></div>
         <div class='face'><iframe scrolling="no" loaded="0" url=""></iframe><div class="label"></div><div class="over"></div></div>
         <div class='face'><iframe scrolling="no" loaded="0" url=""></iframe><div class="label"></div><div class="over"></div></div>
     </div>
 </div>

css3:

     transform: translateZ(-10em) rotateX(360deg) rotateY(360deg);

2.js操作代码

iframe加载操作[缩放iframe大小，默认以1024宽度访问网站]

 $(".cube").find("iframe").each(function(i){
     if(this.attributes.url.value!=''){
     this.style.height = 1024+"px";
     this.style.width = 1024+"px";
     this.onload = this.onreadystatechange = iframeload;
     this.src = this.attributes.url.value;}
 }); function iframeload() {
     if(outFrame===this){return;}
     if (!this.readyState || this.readyState == "complete") {
         this.focus();
         this.style.transformOrigin = "left top";
         this.style.transform = "scale("+targetWidth/1024+")";
         this.style.display="block";
         $(this).attr("loaded","1");
     }
 }

盒子旋转操作

 var overs = document.querySelectorAll(".fix .over");
 for(var i =0;i<overs.length;i++){
     if($(overs[i]).prev().prev().attr("url")!='')
         overs[i].addEventListener("click", mouseclick, false);
     overs[i].addEventListener("mousedown", mousedown, false);
     document.addEventListener("mouseup", mouseup, false);
     overs[i].addEventListener("mousemove", mousemove, false);
 } function mousedown(e){
     mouse.x=e.pageX;
     mouse.y=e.pageY;
     canmove = true;
 }
 function mouseup(e){
     mouse.x=null;
     mouse.y=null;
     canmove = false;
 }
 function mousemove(e){
     if(canmove && mouse.x!=null && mouse.y!=null){
         var ydeg=0,xdeg=0;
         xdeg = e.touches[0].pageX - mouse.x;
         ydeg = e.touches[0].pageY - mouse.y;
         xd =  (xd + xdeg)%360;
         yd = (yd -ydeg)%360;
         e.touches[0].target.parentNode.parentNode.style.transform = "rotateX("+yd+"deg) rotateY("+xd+"deg)";
         mouse.x=e.touches[0].pageX;
         mouse.y=e.touches[0].pageY;     }
 }
